ELECTRIC LOGOMOTIVE.

Application filed January 7, 1911.

To all whom it may concern:

Be it known that I, Gnonen M. EATON, a citizen of the United States, anda resident of WVilkinsburg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in ElectricLocomotives, of which the following is a specification.

My invention relates to electric locomotives and other vehicles whichare propelled by electric motors and it has special refer ence to suchvehicles as are adapted to haul heavy loads at very high speeds.

The object of my invention is to provide a simple and durable journalbox or hearing structure for electric locomotives and other railwayvehicles which shall be laterally restrained at relatively low pointsand therefore specially adapted to reduce the flange pressure usuallydeveloped by locomotives having relatively low centers of gravity.Electric locomotives have usually had relatively low centers of gravity,by reason of the fact that the electric driving motors were located onor near the axles. "When a locomotive of this structure was inoperation, the various movements of its body and frame produced heavystrains in the rails and wheel flanges, which would have been absorbedby the carrying springs of the locomotive if its center of gravity hadbeen relatively high.

In a co-pending application for Letters Patent of John E. Webster,Serial No. 567,- 908, filed June 20, 1910, means is set forth forobtaining somewhat lower points of side restraint for the spring-borneparts of locomotives, by utilizing specially constructed guide ways forthe locomotive journal boxes.

According to my present invention, instead of restraining the journalboxes of a locomotive in the usual manner against lateral. movement, Irestrain each pair of journal boxes from a single point located in thecentral plane of the locomotive and materially below the locomotive axlewith which they are associated, whereby the easy riding qualities of alocomotive having a high center of gravity are secured Specification ofLetters Patent.

Patented Nov. as, 1916.

Serial No. 601,320.

My invention is illustrated in the accompanying drawings of which Figure1 is a partially sectional plan view of a pair of locomotive bearingsand a portion of a locomotive frame constructed in accordance therewith.Figs. 2 and 3 are sectional elevations at right angles to each other ofthe parts shown in Fig. 1.

Referring to the drawings, the structure here shown comprises alocomotive axle 1, driving wheels 2 secured thereto, side frames 3, asingle journal box casting 4:, an equalized side-spring system 3, and apedestal binder casting 4 In accordance with familiar practice, theside-frames 3, and any other so called spring-borne parts that may becarried thereby, are resiliently supported upon the axle 1 by means ofan equalized side-spring system 3 of suitable form.

The casting 4: embodies the axle journal boxes and is provided withdownwardly extending notched projections or jaws 5 and 6, which arelocated on opposite sides of the centralvertical plane of the axle andare provided with shoes 7 and 8.

The pedestal binder casting 1 is provided with end members or binders 9which are bolted to the side frames 3 in the usual manner and aconnecting body member, having laterally extending lugs or projections10 that are slightly tapered toward their upper and lower ends to permitof the usual rolling or rocking movements of the spring-borne parts withrespect to the axles and journal boxes. The lugs 10 project into notchesin the jaws 5 and 6 and engage the shoes 7 and 8.

The shoes are held in place by means of small binders 11 which arebolted to the jaws 5 and 6. The journal boxes are restrained againstlateral movement with respect to the side frames by the engagement ofthe projections 10 with the jaws 5 and 6, which also serve as a pivotabout which the side frames 3 may roll.

By the use of my invention the vertical distance between the center ofgravity and the point of side restraint for the spring borne parts ismaterially increased. The

lateral movements of the locomotive body are therefore largely convertedinto rolling movements which are absorbed by the usual side springs (notshown) of the locomotive, thereby reducing the excessive side thrust onthe wheel flanges.

The side restraining members do not necessarily form 7 parts of thepedestal binder and may be permanently connected to the locomotive framewithin the spirit and scope of my invention.

The parts which cooperate to effect the side restraint may be locatedonly on one side, instead of on both sides of the locomotive axle asshown in the drawings.
